Fundamentals of Operating Systems

Operating systems (their kernel specifically) orchestrate many processes, allow access to memory, disk, network and execute processes by scheduling them to the CPU. Sounds simple when we put it this way but this task is vast. Writing efficient programs depends on how much understanding the engineer has in OS kernel.

When we access a 32 bit integer in memory or write 6 bytes to disk, the kernel and hardware work together through several steps and layers to handle those tasks, simple as may seem. Each step and layer may add unpredictable costs. As a result we as engineers are bound to write inefficient code as we grind across the grain of the kernel.

I built this course to demystify what I believe are the fundamentals operating systems to software engineers. By knowing how the kernel works, you will start writing software differently and naturally as you will start questioning what happens in each line you author.

Like all my courses, I recommend the student having some programming experience to take this course, it just makes the course relatable. The course is focused on Linux but I do explain how Windows and Mac are different in certain situations.

I hope you enjoy it. I'm happy I was able to finish it after 2 years of work.

Everyone should read OSTEP book along with this course its so so gooood

[mayanksharma]

First thing I saw when I opened my machine for the day, is the announcement for the new course on email. Immediately got it and then came to the video. Made my day!
Thanks Hussein!

[rowdyjuneja]

I’ve been waiting for this course for some time now. Thanks Hussein!

[AbderrahimJari-rnep]

Hello, I am a bigenner in this field and I am very excited about this course, I have a lot of questions and I think you will answer them, usually I want to understand all these employees how it works from scratch, how the hardware and software components work together, thank you, I appreciate it truly.

[TechSpot]

Thanks Hussein, for coming up with these amazing courses and providing us this rare knowledge which makes us more confident in our job.❤

[punpompur]

Wow. Finally this course is here. Can't wait to go through this one. Tysm Hussein :)

[violin]

Fantastic stuff!! Can’t wait to try it

[osamaps]

bro your enthusiasm makes me want to jump :)

[anoh]

I have not yet got your courses as I am still just a struggling student but once I get my diploma and my first salary.
I am gonna get ur database and networking and os courses.
I bet I will learn more useful stuff than what I have been learning in university.
Unfortunately the internet is filled with courses that just trap learners into tutorial hell instead of teaching them solid fundamentals....

[shishirchaurasiya]

wow, just wanted to learn about the operating system and boom you launched one and I bought it.

[PavitraGolchha]

Couldn't stop buying this course.

[mohameddiaa]

حابب اشكرك علي المحتوي اللي بتقدمو استفدت كتير وجزاك الله خيرا

[void_star_void]
